Experiment No.1 AMPLITUDE SHIFT KEYING
Experiment AMPLITUDE SHIFT KEYING Aim: To generate and demodulate AMPLITUDE SHIFT keyed (ASK) signal using MATLAB Theory Generation of ASK AMPLITUDE SHIFT KEYING - ASK - is a modulation process, which imparts to a sinusoid two or more discrete AMPLITUDE levels. These are related to the number of levels adopted by the digital message. For a binary message sequence there are two levels, one of which is typically zero. The data rate is a sub-multiple of the carrier frequency. Thus the modulated waveform consists of bursts of a sinusoid. One of the disadvantages of ASK, compared with FSK and PSK, for example, is that it has not got a constant envelope.
